Typical 24 V Current Consumption Of The Components - Siemens Sinamics S120 Manual

*2 The metallic enclosure of the SINAMICS components and the PE connection of the
overvoltage protector must be interconnected in a manner that ensures good conductivity
(equipotential bonding). This can be achieved by installing the SINAMICS components on a
metallic mounting plate and connecting the PE connections of the overvoltage protection
elements as directly as possible to the mounting plate.
*3 Snap the overvoltage protector (MCZ OVP TAZ) onto the metallic DIN rail to make the PE
connection (terminal 5) to the rail. It is then sufficient to establish a good conductive
connection between the DIN rail and the metallic enclosure of the SINAMICS component
(equipotential bonding). This is the case when both the DIN rail and the SINAMICS
component are mounted on a common metal mounting plate.

Typical 24 V current consumption of the components

A separate 24 V power supply must be used for the SINAMICS S120 drive line-up.
The following table can be used to calculate the 24 V DC power supply for the components.
The values for typical current consumption are used as a basis for configuration.
